The DMA860H is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DMA860H can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DMA860H an ideal choice for high requirement applications.
Anti-Resonance provides optimal torque and nulls mid-range instability
Motor auto-identification and parameter auto-configuration technology, offers optimal responses with different motors
Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
